The UK government has published a live queue tracker for people to follow on YouTube. Keep checking that to see where the back of the queue is, as it keeps moving.

Transport into, and across London, is busy – as people travel to the capital to pay their respects, or just come to see the many flowers left for the late Queen.

Transport for London (TfL) said nearly 115,000 more tube journeys were made to, or from, eight stations in the city centre on Wednesday, including Hyde Park Corner and Piccadilly Circus, compared with the same day last week – an increase of 20%.

Green Park station has already had to close on a number of occasions due to overcrowding.

Generally, where possible, the overwhelming advice is to walk within central London – taking in the many sites and tributes as you go.
